Effect of pH on the growth and protein content of dikaryon and fusant protoplast mycelium of Pleurotus sajor-caju at different incubation periods under submerged condition

摘要

In this study the effect of pH on the growth and protein content of dikaryonand fusant protoplast mycelium of Pleurotussajor-caju at different incubation periods under submerged condition was determined sequentially.The respective mycelia were grown separately at 5, 10, 15 and 20 days of incubation period.All those incubation periods were studied at pH 5.0, 5.5,6.0, 6.5, 7.0 and 7.5.The dry weight and protein content of the respective mycelia were determined.The data revealed that the pH 5.5 at 15 days incubation period was the best for the growth of both dikaryon and fusant protoplast mycelia as well as the yield of protein.pH 5.5 also showed best result at different incubation periods of different mycelium.
